Because experiencing a diffraction limited pic is not a black and white thing. The issue would be how much diffraction is going to make a difference on your shots. Not the odd idea that any diffraction at all makes it a reject. Another ongoing LUG Myth. And just as nutty as most of them. You reach a trade off between the DOF you are getting and the loss of contrast from diffraction. And the idea that such a loss of contrast can be put back into the image in Photoshop or Lightroom in about a second and a half.
